Difference between ACL

[silviu1983]

Hy,

I have noticed some difference in creating ACL

i mean i have the following lab

in the upper middle router when i create 

access-list 2 deny 10.90.0.0       0.0.255.255   -   nothing happens , which is as expected

but, when i type

access-list 1 deny 10.90.0.0    0.0.255.255     -  it gets applied imediatelly no matter what i do and i cannot ping from any hosts to any host

so my question is. why acces-list 1 gets applied imediatelly without assign it  on a interface with the 

ip access-group - command?

Hi there,

There is nothing special about access-list number 1.

Can you share the full config of the router with us?

cheers,

Seb.
